5 street, in the city of Montreal, Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in Compounds for Exterminating Vermin; and I do hereby declare that the 10 following is a full, clear, and exact description of the same. 1 1

The invention relates to a compound for exterminating vermin, and the object of the Invention is to devise a means of attracting vermin at nighttime to an. entangling surface,"s'aid surface being equally eflicacious during the'day-time, and generally to provide a simple and convenient means for making sticky -fly paper consists essentially of the novel combination of ingredients to form a compound, both luminous at night night. of the compound is a preferably made up of resin or any resinous substance and castor oil, though there are several formulas for a fly paper sticky substance and almost any one of these may be used, themain feature One of the arts 0 being-to provide a viscous composition. In

rsome cases pet-rolatum,

may be added to the resin in place of castor Vaseline or glycerin oil, anyway it is most likely to be resin and an oil product for in those two ingredients,

for a good entangling efiect can be most easily reached. The other ingredient of the compound is any luminous substance compounded or simple, that is to say, a substance which gives forth 3 light at night-time, or in the dark. The

particular ingredients of'this luminous substance are not essential to the invention, though it has been proved that the most adaptable substance to mix with the viscous i substance is that made up of luminous sulfid of calcium (mono-sulfid CaS, which is usually produced by heating powdered oyster shells and sulfur together in a closed crucible,) the powder may be mixed with another ingredient, such as sulfid'Iof-barium, before being added to the viscous substance or be in the form of luminous paint. Any small departure in regard to the mixing of these ingredients is not materially con- ,cerned in the proper working out of this invention, so long as the efi'ective luminous substance is mixed with the viscous composition.

A very good addition to the luminous substance 1s a zinc salt or compound for a col.- oring matter, as this produces a blue light extremely efl'ective in the attraction of insects.

It is possible, of -course, to use phosphorus, but on account of its poisonous properties, it is advisable to avoid it, besides the best compound is made with the luminous sulfid of calcium, sulfid of barium and per haps a gum varnish together with the resin and oil product. i

In the uses of this invention, the substance is preferably contained in tins, thor oughly sealed and sold in small packages so that the consumer can buy a small package and spread the viscous or sticky substance over any sheet of paper or in fact many forms of suitablebacking, further the substance may be spread over the branches and trunks of fruit trees and attract the inoltlhs at night-time by the radiation of the 1g t.

There are many uses to which this invention may be put, but naturally the main object is the general use fortrapping flies and so avoiding that household nuisance and this is probably the cheapest and cleanest form in which asticky fly paper can be supplied to the ublic. I p What I claim as my invention is: 1. A compound for exterminatin vermin, consisting of a sticky and substantially nondrying mixture of a resinous substance and an oil product,and a luminous substance.

2. A compound for exterminating vermin,

consisting of resin and castor oil, and a lu-. mlnous substance, mlxed together.

3. A compound for exterminating vermin,

consisting of a sticky and substantially nondrying VISCO'US substance and luminous sulfid of, calcium and sulfid of barium, mixed together.

4. A compound for exterminating vermin, consisting of a sticky and substantially nondrying viscous composition and luminous sulfid of calcium, sulfid of barium and a gum varnish, mixed together.
